Well differ with you strongly on that. Prior to this run, his best form was probably before the shoulder injury in 2019. He neither was as prolific nor so consistent at causing chaos amongst top defenders.
Rashford's been scoring more goals during this current period, but I'd still say his all-round performances were better in 19/20 before the injury. He was so dangerous in basically every aspect, with his dribbling, passing and crossing all being better than what he's shown this season. He was genuinely terrifying defenders on the regular, whereas this season he's actually had a lot of games where he hasn't really played that well but has popped up with a goal. Obviously he's had some games where he's been truly good in all aspects, but not as many IMO.
In saying that, he did have a fit and firing Martial to combine with back then, which is of course very different than trying to do it with Ronaldo or Wout like he's had to do this season. An in-form Martial tends to bring out the best in all our attackers, which is why it's so disappointing that Rashford is injured just as Martial seems to be back. Seeing as this is an Antony thread though, hopefully Antony (and Sancho) can take advantage of his return.
